如何实现状态栏文字自左向右滚动效果

问题描述：

从右向左的效果代码为：
<script>
<!-- Beginning of JavaScript Applet -------------------
function scrollit_r2l(seed)
{ var m1 = "欢迎光临。谢谢!" ;
var m2 = " " ;
var msg=m1+m2;
var out = " ";
var c = 1;
var speed = 120;
if (seed > 100){
seed-=2;
var cmd="scrollit_r2l(" + seed + ")";
timerTwo=window.setTimeout(cmd,speed);
}
else if (seed <= 100 && seed > 0)
{
for (c=0 ; c < seed ; c++)
{out+=" ";}
out+=msg;
seed-=2;
var cmd="scrollit_r2l(" + seed + ")";
window.status=out;
timerTwo=window.setTimeout(cmd,speed);
}
else if (seed <= 0)
{
if (-seed < msg.length)
{
out+=msg.substring(-seed,msg.length);
seed-=2;
var cmd="scrollit_r2l(" + seed + ")";
window.status=out;
timerTwo=window.setTimeout(cmd,speed);
}
else
{
window.status=" ";
timerTwo=window.setTimeout("scrollit_r2l(100)",speed);
}
}
}
scrollit_r2l(100);
</script>
但我想实现从左向右怎么改？
麻烦知道的各位告诉一下。
